Specification of Letters Patent.

Patented Sept. 1'7, 1907.

Application filed April 19, 1906- Serial No. 312,725.

To all whom it may concern:

Be it known that 1', SAM GWYN SCANLAN, a citizen of the United States, residing at Madison, Dane county, Wisconsin, have invented a new and useful Improvement in Surgeons Operating-Tables, of which the following is a specification.

My invention relates to improvements in surgeons operating tables which are constructed to present' the body of the patient in advantageous positions for the surgeon; and the objects of my improvement are, to provide means by which the central portion of the pa tients body can be raised relatively higher than either of the extremities; also to provide means by which the shoulders of the patient can be elevated and the head thrown back and lowered relatively tothe shoulders, for especial advantage in operations on the throat; also, to provide means whereby the position of the table may be quickly reversed while the patient is on the table, and in the course of the operation, from what is known as the Trcndelonburg position, to a position in which the abdomen of the patient is lowered relatively to the extremities; also, to provide a table capable of these adjustments which will combine the greatest possible amount of rigidity and firmness, which will be free from parts dii'licult to keep clean and aseptic and which can at the same time be constantly under the control of the anesthetizer for ready adjustments of position when required during the COUISG of the operation. I secure these objects by the device shown in the accompanying drawing, in which,

Figure 1, is a perspective view of the operating table showing four different possible positions of the table. Fig. 2, is a perspective view of the table showing another possible position of the table, showing also the method of controlling the position of one of the parts of the table top, and illustrating to better advantage the means of adjusting the table top in certain positions.

The top of the table is constructed in two main sections. One section consists of the parts numbered 1 and 2; the other section consists of the parts numbered 3 and 4; the main support of the table top is the upright posts, 5, on which the table top rests and on which the top is pivoted at 6. The whole is supported by a base of any desired construction, but preferably constructed of iron pipe posts, 7, and top pieces, 7 and 7, and braced to give the required strength. I

The position of that section of the top which consists of parts, 1 and 2, is controlled by the slotted guide arms, 8, which arms are fastened pivotally to the table top at 8; these arms are slotted at 8 to pass the lock nut,

I 9, and are fastened adjustably to the supporting base,

7 by the lock nut arrangement, 9.

The controlling arm, 10, is below the table top, and is fixed rigidly to the part, 1, of the table top at 10; 11, is a slotted guide arm connecting the controlling arm 10, with the controlling arm, 12, which latter arm is fixed rigidly to the part, 3, of the table top at 12, and is below the table top. The guide arm, 11, is slotted at 11 to pass the lock nut, 13, on the controlling arm, 10 and to be adjustably fastened to the arm, 10, by the lock nut, 13. Guide arm 11 is also pivoted on the controlling arm, 12, at 12; this adjustment serves both to assist in controlling the relative positions of the parts 1 and 3 of the table top, and also, to add materially to the firmness and rigidity of the table top.

Extending between the top bars, 7 of the base of the table, and the support posts, 5, is a curved brace, 14, making the posts 5 more rigid on their base. This brace, 14, is notched as many times as may be desired, as shown at 15.

Located between the bars, 7 of the base of the table, and extending up between the braces, 14, are two adjustable braces, 16, pivoted at 17 near the foot of the upright posts, 5, and slotted at 16 to receive the cross bar, 15 these braces meet metal plates on the under side of the part, 3, of the table top; by means of the cross rod, 15, operating in the slot 16 of the braces, 16, and projecting beyond the outside of braces 16 so as to engage notches, 15, in the braces, 14, the braces, 16, may be set to lift the part, 3, of the table top to certain positions, such as is shown in Fig. 2, in a very simple and rapid manner, thus controlling the relative position of the part 3 of the table top at various angles to the part, 1, of the table top.

The part, 3, of the table top is hinged on the part 1, of the table top, at 18, and the part, 4, of the table top is hinged on the part 3 of the table top at 19. Along the center, and on the under side of the part, 4, of the table top, is a bar, 20, (shown in Fig. 2), forming a part of the frame of the part 4, and notched on its under side at 20 (Fig. 2) to engage the end of the brace rod 21 which is pivoted at 21 t0 the controlling arm, 22; the controlling arm, 22, is fastened rigidly at 22 to the part 3 of the table top; 23 is a gravity counterweight on the end of the brace rod, 21, to keep the brace rod, 21, always in position to engage the notches, 20 on the under side of the bar, 20.

The part, 2, of the table top is hinged on part, 1, at 2 to permit the adjustment of part 2 at any desired posi: tion at an angle abovethe level of part, 1, of the table top for a head piece; on the under side of the part 2 of the table top is a curved support bar, 24, hinged to the head-piece 2, and in a position so it always falls into position against the rod, 25. The bar, 24, is notched at 24 to engage the controlling rod, 25, which is fastened rigidly to the under side of part, 1, of the table top, thus making it possible for the part, 2, of the table top to be raised or lowered relatively to the part, 1, of the table top.

26, is an arched rod attached rigidly to the end of part 1 of the table top to serve as a handle in adjusting the relative positions of the parts 1 and 3 of the table top.

The operating table is shown in adifferent position, being a perfectly straight inclined plane, by the dotted lines between 28 and 29, in which case the braces, 16, take the position shown by dotted lines extending from 17 to 17 The part, 4, of the table top is shown in a relatively different position by the dotted lines extending out from 19 to 30.

The method of use and the advantages of the table are as follows:1f the table is in the position shown in Fig. 1, or, if it is in what is known as the Trendelenburg position, the anesthetizer, may, while the patient is on the table, loosen the lock nut, 13, then grasp the handle, 26, on the part, 1, of the table top, then loosen the lock nut, 9, and by merely raising the part, 1, by means of handle, 26, or otherwise, to the position showii in Fig. 2, the part, 3, of the table top is of necessity in the one movement driven to the relative position shown in Fig. 2, and held there by merely tightening the lock nut, 9, then, by tightening the lock nut, 13, the table is made doubly rigid and firm.

All the controlling parts of the table are of the utmost simplicity and are arranged so as to be near the part, 2, on which the head of the patient usually rests, and opposite which the anesthetizer stands during the operation, giving him instant. and convenient control of the adjustment of the table.

The table is free from annoying gears and cranks and chain drives which are apt to retain infection, and are diflicult to keep clean and aseptic.

The whole table top is pivoted on the supporting base, simplifying its control, and making possible instant reversing from one inclined plane, as is shown in Fig. 1, by the dotted lines, 28 and 29,'to the direct reverse shown from 26 to 18, and by dotted lines to 31, by merely loosening one lock nut, 9, and swinging the whole table top to the new position; and also making possible the instant and simple reversing from the position shown in Fig. 1, to the position shown in Fig. 2, as above described.

By proper placing of the patients body on the table, any portion of the body may be raised relatively to the remainder of the body, as for instance the shoulders raised and head lowered for throat operations.

What I claim and seek to secure by Letters Patent,

1. The combination with a frame of a main table section pivoted thereon and having curved slotted arms, clamping means on the frame for engaging said slotted arms for adjusting said section relative to the frame; an intermediate section pivotally supported from the frame and hinged to the main section, links pivoted to the intermediate section and connected to the main section for adjusting said sections about their hinge; a third section pivoted to the intermediate section, and means for adjusting the latter sections relative to each other.

2. The combination with a main section pivoted to a supporting frame and means for adjusting the section relative to the frame; of a two piece member hinged to said section; one of said pieces pivotally supported from the frame and having pivoted slotted arms which are connected to the main section, and clamps on said slotted arms for-holding the two piece member in adjusted position relative to the main section.

3. In a surgical table, a frame, a main top section piv oted near one end on the frame and having an adjustable head rest pivoted thereto near the other end, means for adjusting said main section with respect to the frame, a supplemental top section pivotally mounted on the frame and formed of two members hinged together, means for adjusting said members with respect to each other, and slotted links pivoted to one of said sections and adjustably connected to the other of said sections for adjusting the main section and the supplemental section relatively to each other.

4. The combination with a table frame of two sections hinged together and pivotally supported on the frame,

slotted arms attached to the main section and connected adjust-ably to the frame for adjustment of the main section, means for adjusting; the second section relative to the frame, and slotted arms pivoted to the second section and connected to the main section for adjusting the second section relatively to the main section.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

SAM GWYN SCANLAN.
